Browser to dump an entire SILO file?

[wnissen]

Hi, @markcmiller86 et al.,

I can use browser to print the value of a particular variable, e.g.:

> browser --eval=MMESH Disk2D/OvlTop.silo
INFO: opening `Disk2D/OvlTop.silo' as $1
                              = DBmultimesh: struct
id                            =    0
[...]
groupnames                    =    NULL

Is there a command or recipe to (hopefully recursively) dump all the variables contained within a given SILO file?

Thanks!

@wnissen I think you might be able to diff the file with itself and have it print everything, not just diffs. Lemme try.

[markcmiller86]

@wnissen ok, that doesn't work. When the file is diffed with itself, all the diffs are zero and I cannot set a negative tolerance. If it is a Silo/HDF5 file you can use HDF5 tools (h5ls and h5dump). But, you wind up having to understand a bit about the internals of how Silo writes its high level objects to HDF5.

Another option is to use Silo's python interface and write a small amount of python code to do it....recursively using Silo.SetDir() and Silo.GetToc().

Thanks, Mark, I figured if anyone knew the shortcut, it would be you. I can write something fairly straightforward in Python.

@wnissen you may be able to use Conduit's Silo / Overlink support to read in two files and do a full diff of fields.

[wnissen]

@cyrush Do I do that with the Conduit Python? Is there an example of reading and/or diffing using that? Thanks.

Looks like this is quite easy to dump the Conduit, that is just as good if not better than the browser output.

>>> import conduit
>>> node = conduit.Node()
>>> conduit.relay.io.silo.read_mesh(node, 'Disk2D.silo')
>>> node.print_detailed()
